. .MOLDING.

a K -k fl an entree PM W CHARLES JELLINEK, OF NEW YORK, N. 21, ASSIGNORF QNE-THIRD T0 SAID JELLINEK, GEE-TH T0 DAVID STERN, AND ONE-THIRD TODAVID WALD, ALL OF NEW YORK, N. Y.

To all whom it may concern:

Be it known that l, CHARLES JELLINEK, a citizen of the United States,residing at the borough of Manhattan, in the city, county, and State ofNew York, have invented an Improvement in Moldings, of which thefollowing is a specification.

Heretofore it has been customary, in running electric circuit wires onthe exterior of walls, as well as similar places, for the purpose ofelectric lighting, or otherwise, to

as far as possible, the fire risk, due to short circuits, it beingunderstood that the metallic molding is required to be suitablygrounded, in order to carry any stray currents to earth.

I am aware that vario is forms of metallic moldings have been made andused, but all of them are, I believe, necessarily expensive, as comparedwith the old form'of wooden molding.

Now, the object of my present invention is the provision of acomparatively inexpensive moldi'ng'which will ineet all the requirementsof the underwriters and various municipal building departments relatingto a metallic conduit for electric circuit wires.

In carrying out my present invention, 1 preferably employ the ordinaryform of wooden molding, fitting the same with a metallic facing,provided with a metallic lined cover, so that when the parts are placedtogether they form acomplete metallic conduit for the reception ofelectric circuit wires. 1 also employ the necessary bond members forconnecting the otherwise separated metallic parts of the molding,

made in accordance with my invention, so

that the molding may be suitably grounded like a completely metallicconduit.

molding, Fig. 3 is a perspective View show ingthe construction of themolding made for running conduits on exterior surfaces, and Fig. 4c is across section illustrating one manner in which the metallic facing maybe secured to the base of the molding.

Referring to the drawing, and particularly to Fig. 1, the molding madein accordance with my present invention comprises a base 10, made ofwood or similar material, in strips of suitable lengths and provided, asis customary, in such molding, with longitudinal grooves 11 in onesurface thereof. Together with this base, facing 12 made of sheet metal,formed with grooves 13 adapted to fit and lie within the grooves 11 inthe face of the base 10, the

opposite edges of the metallic facing 12 being inturned and set into,grooves provided therefor in the opposite edges of the base l0, as shownin Fig. 4. Together with each strip-of molding so constructed, 1employ'a .cover, indicated at 15. This is also made of.

wood, or any similar material, and on one side thereof is provided witha metal face- This is made of metal and comprises tongues 18 and 19, atright angles to each other, adapted to lie against the surface of themetallic lining between the grooves in the molding and to be securedthereto by screws or nails 19 or otherwise. At the corners this ll alsoemploy a bond member is provided with ears 20, in

which there are grooves 21, which, as will be understood, extend overthe edges of the metallic facing at the ends of the strips of molding,where the joint is made, at which place these edges, because of beingcut to .form the joint, may be more or less rough and thus apt to breakor injure the insulation on the circuit Wires, these grooved ears 20covering the. rough edges of the'metallic face, so as'to prevent anypossible injury to the insulation of the wires. A similar bond member isshown in Fig. 3, for use in running circuit wires on the exteriorofwalls and ceilings or floors. This bond member, as indicated at 22, isprovided with tongues 23, which are secured to the metallic facing ofthe molding by means of screws or nails 24:, and at theangle or bendthis bond member is provided with cars 25 having grooves 26 fitting intothe grooved portions of the adjacent members of the molding. Also asindicated'in Fig. 2, the bond member employed in the use of my improvedmolding may comprise a flat strip of metal, as indicated at 27, theopposite parts of which form tongues 28, and may be secured to themetallic facing of adjacent strips of metal by means of screws or nails29. lhis bond member is also centrally provided with; ears 30, in whichthere are grooves 31, adapted to be fitted into the grooves in theadjacent sections of the molding and covering the rough edges thereof inthe same manner as the similar parts of the other forms of bond membershereinbefore described are designed to do.

By reference to Fig. 2, it will also be seen that I may employ aterminal member 32, provided with a contact 33 adapted to receive oneend of a wire 34, by means of which the molding may be suitably connected to the ground. o

It will also be understood that my invention is not limited to theprecise form of molding hereinbefore described and illustrated in thedrawing, nor to the particular forms of bond members as described inconnection therewith, as other forms of molding and bond members may beemployed, coming within the terms of the claims, without departing fromthe nature and spirit of my invention.

1 claim as my invention: I

1. A molding for electric wiring, comprising a Wooden base havinggrooves in one face thereof, a metallic facing having grooves thereinfitting into the grooves in the said base and secured at its oppositeedges in the adjacent parts of the said base, and a bond member forconnecting together electrically adjacent sections of the molding.

2. A molding for electric wiring, comprising a wooden base havinggrooves therein, a metallic facing also having grooves therein adaptedto fit Within the grooves in the said base and secured at opposite edgesto the adjacent parts of the said base, a bond member having tongues forconnecting the same to the metallic facing of adjacent sections of thesaid molding, and grooved ears fitting into the grooves thereof to coverthe edges of the metallic facing at the joints between the sections.

Signed -by me this 2 lth day of March, 1914.

CHARLES JELLINEK.
